Ahhh, the first episode. So much eye candy and the animation quality was really great.
Music was good, and I remember getting addicted to the "Motekke" part of Iteza here.
As for the characters, my initial impressions were:
Alto = TILF (Trap I'd Like to F*ck)
Ranka = Another girl-next-door loli-moe
Sheryl = Stripperella bitch
Cathy = HOT HOT HOT <--- I also thought she would be Sheryl's rival. X'D
Vajra = Space Lobsters
I am still amazed when I look back at how different my impressions and opinions were compared to now.
